Two symmetrically arranged hot pressing brackets are arranged at the bottoms of both ends of the synchronous block. Two symmetrically arranged third rotating shafts for fixing the heat insulation film are arranged between the hot pressing brackets. The hot pressing port of the hot tool is attached to the center line of the heat insulation film.

Inside the rear frame and on one side of the double-pressure roller, a rotating roller driven by the motor is arranged. The double-pressure roller is in contact with the rotating roller. Guide rollers are arranged on both sides of the double-pressure roller and the rotating roller. During use, the double-pressure roller applies a constant pressure to the rotating roller under the action of the second cylinder and the swing arm. The motor drives the rotating roller to drive heat-sealing composite films such as plastic film substrates, soft packaging composite films, or coated papers that need to be heat-sealed to be delivered forward along the direction of the guide rollers. Since the material will pass through the contact area between the rotating roller and the double-pressure roller during the delivery process, when the hot knife presses down on the material, if the material shrinks due to heat and adhesion, the material will be subject to the pressure of the double-pressure roller and the friction between the double-pressure roller and the rotating roller, preventing the material from retreating backward due to its own elasticity and affecting the heat-sealing work.
[0015] A storage device is arranged between the correction and deviation rectification device and the feeding and traction device. The storage device includes a row of several upper storage rollers. Lower storage rollers are arranged below the upper storage rollers in an alternating manner. The lower storage rollers are fixedly connected with swing arms. One end of the swing arm far away from the storage roller is rotatably connected with the front frame through a pin shaft. When the first servo traction device and the second servo traction device stop working, the swing arm will rotate downward with the pin shaft as the axis. When the first servo traction device and the second servo traction device start working, the swing arm will rotate upward with the pin shaft as the axis to keep the material in the storage device taut.
[0016] The beneficial effects of the present utility model are as follows: the corresponding position between the material and the servo cutting tool can be changed by adjusting the height of the adjusting roller, which is convenient to use. In addition, when the feeding traction device keeps delivering and the first servo traction device and the second servo traction device stop working temporarily, the rocker arm in the storage device can keep the material taut, preventing the material from wrinkling and stacking. During transportation, the first photoelectric tracking device and the second photoelectric tracking device are used to detect whether the material is offset. If the material is offset, the feeding deviation rectifying device and the correction deviation rectifying device are used to straighten the conveyed material. Brief Description of the Drawings

[0035] A second servo motor 713 is provided outside the rear frame 13. The second servo motor 713 is drivingly connected to the second rotating shaft 702 through a belt 714.

[0039] A hot pressing workbench 15 for cooperating with the servo hot pressing device 7 is arranged below the servo hot pressing device 7. The hot pressing workbench 15 includes two symmetrically arranged fixing frames 1501. The fixing frames 1501 are inclined and arranged on the rear frame 13. A second cylinder 1503 is fixedly connected to the fixing frames 1501. The movable end of the second cylinder 1503 is supported and connected with a swing arm 1505.

The double pressure roller 1507 is in contact with the roller 1504. Guide rollers are arranged on both sides of the double pressure roller 1507 and the roller 1504. During use, the double pressure roller 1507 applies a constant pressure to the roller 1504 under the action of the second cylinder 1503 and the swing arm 1505. The motor 1508 drives the roller 1504 to drive heat-sealing composite films such as plastic film substrates, soft packaging composite films or coated papers that need to be heat-sealed to be delivered forward along the direction of the guide rollers. Since the material will pass through the contact part of the roller 1504 and the double pressure roller 1507 during the delivery process, when the hot knife 718 presses down on the material, if the material shrinks due to heat and adhesion, the material will be subjected to the pressure of the double pressure roller 1507 and the friction between the double pressure roller 1507 and the roller 1502, preventing the material from retreating backward due to its own elasticity and affecting the heat-sealing work.
[0040] A storage device 16 is provided between the correction and deviation rectification device 3 and the feeding and traction device 2. The storage device 16 includes a row of several upper storage rollers 1601. Below the upper storage rollers 1601, there are lower storage rollers 1603 arranged staggeredly with the upper storage rollers 1601. The lower storage rollers 1603 are fixedly connected to a rocker arm 1602. One end of the rocker arm 1602 away from the storage rollers 1601 is rotatably connected to the front frame 12 through a pin shaft. When the first servo traction device 4 and the second servo traction device 9 stop working, the rocker arm 1602 will rotate downward with the pin shaft as the axis. When the first servo traction device 4 and the second servo traction device 9 start working, the rocker arm 1602 will rotate upward with the pin shaft as the axis to keep the material in the storage device 16 taut. Specific embodiment
[0041] The material is transported forward under the action of the first servo traction device 4, the second servo traction device 9 and the hot pressing workbench 15. During the transportation process, it is detected whether the material deviates through the first photoelectric tracking device 6 and the second photoelectric tracking device 1202. If the material deviates, the material is corrected through the action of the feeding deviation rectification device 1 and the correction and deviation rectification device 3. When passing through the reserved punching device 5, the material is punched. The material is heat-sealed through the servo hot pressing device 7. Then, the height of the adjusting roller 807 is adjusted to adjust the cutting position on the material. Finally, it is discharged through the discharging table board 11. Since when the servo cutter 10 cuts downward, the reserved punching device 5 punches holes and the servo hot pressing device 7 performs heat sealing, the first servo traction device 4 and the second servo traction device 9 will stop briefly, while the feeding and traction device 1 will keep delivering. The rocker arm 1602 in the storage device 16 rotates downward with the pin shaft as the axis. When the first servo traction device 4 and the second servo traction device 9 start working, the rocker arm 1602 will rotate upward with the pin shaft as the axis to keep the material in the storage device 16 taut.
[0042] This design is ingenious. The corresponding position between the material and the servo cutter can be changed by adjusting the height of the adjusting roller, which is convenient to use. In addition, when the feeding and traction device keeps delivering and the first servo traction device and the second servo traction device stop working briefly, the material can be kept taut through the rocker arm in the storage device to prevent the material from wrinkling and stacking. During transportation, it is detected whether the material deviates through the first photoelectric tracking device and the second photoelectric tracking device. If the material deviates, the transported material is corrected through the feeding deviation rectification device and the correction and deviation rectification device. The pressure of the hot knife pressing down can be precisely adjusted through the first air cylinder to adapt to different materials.
[0043] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
